This paper presents a non-uniform meshed embroidered structure for wearable microstrip patch antennas. The non -uniform meshed patch
antenna (NMPA) has significantly less conductor coverage than a conventional patch antenna without significantly compromise the antenna performance. For wearable
applications, less conductor coverage reduces the usage of the specialised conductive materials which are currently expensive. The embroidered NMPA reduced manufacturing cost and improves the flexibility. In this paper, the surface current distribution and the effect of the meshing size of NMPAs have been
simulated and analysed. Fully textile embroidered NMPA on felt substrate has been fabricated and measured. Representative results showed the NMPA had a 60% total antenna efficiency with 20% conductor area
coverage.
